This study was carried out to evaluate graft-taking rates between some environmental factors and grafting seedlings of Pinus densiflora for. multicaulis. Pinus thunbergii seedlings were treated by straw mulching and plastic wind-break treatments before grafting. Temperature and humidity were measured for grafting time. Soil property was analyzed from poor and good sites. Graft-taking rates of the seedlings were significantly higher in wind-break than in straw mulching treatments. However, graft-taking rates of the seedlings were not correlated with temperature and humidity for the grafting time, While were significantly correlated with the day of year. Soil property was not correlated with the grafting rates of seedlings. Soil bulk density and infiltration rates were slightly higher in poor than in good sites, but were not significantly different between both sites. Soil three phase and soil particle distribution were not significantly different between both sites. Soil chemical proeprty was similar between both sites. The results suggest that graft-taking rates in the grafting seedlings of Pinus densiflora for. multicaulis were not affected by environmental factor for grafting time and soil property of the site, but could be attributable to grafting skills and property of scions and stocks.
